6.1.4 Removing a fuel injection pump
The procedure to remove a fuel injection pump from the gear case is shown.
[NOTICE]
Be sure to remove a flange and a fuel injection pump
drive gear with a pair without loosening the flange
bolts.
1) Remove fuel injection pipes, fuel pipes and a
remote control wire. Block the entrance with tape
so that trash may not enter the fuel injection pipes
and the fuel injection pump.
2) Mark the position of the timing marks of a fuel
pump and a gear case. Or, put a mark on the
gear case at the position to agree the timing mark
of a fuel pump.
3) Remove a pump cover from the gear case.
4) Give the marks on a fuel injection pump drive gear
and a idle gear with paint or the like.
5) Loosen fuel injection pump installation nuts (three nuts).
6) Loosen a installation nut of a fuel injection pump drive gear.
7) Pull a fuel injection pump drive gear and a flange with a pair to your side by gear puller.
8) Remove a pump drive gear nut and a washer.
9) Remove a fuel injection pump. Leave the pump drive gear in the gear case.
6.1.5 Installing a fuel injection pump
[NOTICE]
• Use a new O-ring on the fuel pump flange and apply grease.
• Confirm whether the marks of the pump drive gear and the idle gear is correct.
1) Turn a camshaft so that the key of the pump camshaft may almost agree in a position of the key
groove of a pump drive gear.
2) Insert a fuel injection pump into the installation hole of the gear case straight to prevent the
damage of the O-ring. Insert a fuel pump while confirming whether the key of a camshaft and the
key groove of a drive gear agree.
3) Assemble a pump drive gear nut and a washer together temporarily.
4) Turn a fuel injection pump to the position where the marks of the fuel injection pump and the gear
case agrees.
5) Fasten pump installation nuts (three nuts) on the fuel injection pump.
6) Tighten the pump installation nut by the specified standard torque.
